3 Claims.

The invention relates to a vessel'for shaking,

mining, cooling and storingy liquids, and belongs to the iclass commonly known as cocktail Shakers or liquid coolers. l Aprincipal object of our invention is to provide a vessel in which'the ingredients of beverages may be mixed and cooled, and in ywhich Vessel :such mixture may be concocted for immediate or future consumption, the beverages being maintained at their cool temperature for long periods of time, in case the same are not immediately consumed.

Another principal object is to provide means whereby the water from the melted ice may become part of the beverage, or be kept separate therefrom, depending upon the immediate wishes of the Aprospective partaker thereof.

Another principal object is to adapt the ice chamber to beso tightly sealed as to protect the beverage from receiving accretions from the ice chamber, whichis particularly desirable when salt or other freezing mediums are introduced into the ice chamber to'br'ing about sub-freezing temperatures'to'cause mere rapid heat absorption byv the water ice.

Another principal'object is to provide a swinging turret at the head of the vessel, having a pouring spout adapted'to communicate with `and be shut off from thelinterior of the Vessel.

Another principal object is to protect the vacuum element of the vessel from-damage by preventing the ice, when agitated due to shaking ,the vessel, from striking the same.

Other objects will be apparent from reading this specification in connection with the accompanfying drawing, .in which,

Figure 1 is a side elevation in cross-section of a vessel embodying the'invention;

Figure Zlis a cross-'section of the vessel taken along .the line 2--2 of Figure 1, looking in the direction of the arrow;

Figure V3 is a cross-section taken along the line 3-3of Figure 1, looking'in the direction of the arrow;

Figure 4 is a modication ofthe -ice chamber used in our vessel; Vand Figure 5 is a verticalcross-'section showing a modified 'sealing vmea-ns for the cap or closure of the vessel.

Referring now in detail to the drawing, in which similar characters refer to like parts throughout, ID represents the outside shell of the vessel, II the base thereof, and I2 the handle. At the top of the shell IIJ, is screwed the annular collar 22, angular in cross-section, which collar is partially faced by the angulairing 30, preferably of stainless steel, which ring is held in position between vthe packing ring I'I and a portion of the collar 22, thereby protecting Said collar from the liquid contents of the vessel. Pressed into ,the ring 30 is the neck 23, in which is .located the ,port 25 and the air vent 33. Surrounding the neck 23 is a swinging sleeve 35, on which is carried the spout 24, and in which is located the vent 34. Upon the swinging of the spout 24, which may be done manually, the sleeve 36 to'which it is attached, will be carried with it, moving on the stationary neck 23, and

the port Z5 will cease to register with the spout 24,

and simultaneously the air vent 34 will cease to register with the air vent 33. A reverse movement of :the spout 24 will simultaneously register the port 25 with said spout, and the vent 34 of chamber I5. This vacuum chamber is mounted "2- on a shock-absorber I6 at its lower end, and in a resilient ring II at its upper end, to adapt the vessel to sustain shocks without injury to the vacuum chamber.

lThe inside wall I4 ofthe vacuum chamber is provided with alevel gauge I8, which may be in the form of a series of bosses, as shown, or may consist of an embossed ring extending in a circuit around the chamber I3, or may consist of any other form .of gauge, the purpose of which is to indicate ythe height to which liquid contents of the vessel may be brought without possibility of loss through displacement when the ice chamber has been inserted in place in the vessel.

Suspended in the vessel is the ice chamber 21, having an annular iianged top 28, which rests in a recess in the rim 29 ofthe mouth of the vessel. In Figure 4 a modification of theY ice chamber is shown, in which the wall has apertures 35.

In Figure 5 a modified form of sealing means is shown in association with the cap 2G. In this construction there is provided a dished disc 31, in the form of a shallow truncated cone,

having a central bolt 38 integrated therewith to make the same leakproof at the joint of said bolt with the disc. The bolt 38 extends upwardly through the cap 26, and is secured to the cap by the knob 39 which is screwed onto the bolt. The opening for the bolt in the cap 26 is large enough to permit of a limited amount of play between the shank of the bolt and the cap. Furthermore, the knob into which the bolt is screwed has a threaded portion which is closed at the top, and which permits the knob to be screwed down onto the bolt only to a position short of clamping the cap. The result of this construction is that the disc 31 acquires a limited free movement with reference to the cap until the' cap is screwed down, which movement is designed to insure the automatic adjustment of the disc in the rim of the vessels mouth most effectively when the cap is screwed onto the neck 23 of the vessel. The rim of the disc is preferably stepped-up as shown in Figure 5, and mounted on this rim is a gasket 40 occupying the stepped-up relation to the disc, also as illustrated in Figure 5, and forms a seal between the cap 26, the rim of the vessels mouth, and the mouth of the ice chamber.

The outer elements of the vessel are preferably screwed together to permit disassembling of the same for cleaning purposes, the base Il being screwed to the bottom of the shell and the collar 22 being screwed to the top of the shell. The neck 23 is pressed into the collar 22, and the cap 23 is screwedto the top of the neck 23.

In use, the cap 26 is removed, and then the ice chamber, if of the non-aperture form, is removed or raised and the liquid ingredients of the beverage are poured into the mixing chamber I3. If the ice chamber used is of the aperture form, it is not necessary to disturb its position when pouring the ingredients into the mixing chamber. Ice may be placed into the ice chamber either before or after the ice chamber is replaced, and when replaced, the cap is screwed into position.

Where the seal shown in Figure 5 is used, the gasketed rim of the disc finds its position on the recessed rim of the vessel neck 23, by the cap 26 being placed in position on the mouth of the vessel and screwed down upon the vessel neck 23. The pressure of the .cap 26 upon the disc 31 is initially at a comparatively small area of the disc which is adjacent to the middle portion of the cap. Upon pressure being exerted at this area, Vthe same will readily be transmitted to the rim, and because of the loose relationship of the disc with the cap, will readily adjust itself snugly at all points of the rim of the vessel neck, where the seal is designed to take effect.

If it is desired to quickly cool the liquid, the non-perforate form of ice chamber is used,Y and salt or other heat-absorbing medium is supplied to the ice chamber with the ice, before the chamber is sealed in the vessel. If, however, it is desired to mix the water from the ice with the beverage, and ultra rapid cooling is not required, the aperture form of ice chamber may be used.

The gauge I8 is so located in the exposed side of the inner wall of the vacuum chamber, as to indicate the level to which the liquid mixture to be treated in the vessel may be supplied thereto without wastage, before inserting the ice chamber to its service position. The displacement of liquid eilected by the insertion of the ice chamber will, as a result of keeping the liquid level no higher than the gauge line, raise such liquid level without overflow, and in addition, provide operating space inthe vessel to properly mix the contents.

` When the vessel has been supplied with the ingredients to be treated, and ice has been put into the chamber, together with other freezing mediums'when desired, the Vessel may be allowed to stand until the desired cooling is effected, or it may be shaken in the usual way.

When the mixed contents are ready to be consumed, the spout 24 is manually swung to register with the port 25, the vents 33 and 34 then being in register with each other, and the contents may then be poured from the vessel.

Inv the event it is not desired to use all of the contents of the vessel immediately, they may be maintained at a cold temperature by remaining in the vessel until the same are used. Furthermore, it is often desirable to mix cocktails several hours before they are consumed, as for instance, Where they are to be used on a picnic, and the vessel above described is ideal for such purpose, as the beverage is maintained at its cold temperature until used.

.We have shown and described what we believe to be the best embodiment of our invention. We do not Wish to be confined in patent protection. however, to such embodiment, but what we desire to secure by VLetters Patent is set forth in the appended claims.
